These platforms don’t come pre-installed in tsuru, you have to add them to your
server using the platform-add command in
tsuru.

For example, to install the Python platform from tsuru’s platforms repository
you simply have to call:

tsuru platform-add python

If your application is not currently supported by the platforms above,
you can create a new platform. See creating a platform
for more information.

Attention

If you have more than one Docker node, you may use docker-registry to add and distribute your
platforms among your Docker nodes.

You can use the official docker registry or install it by yourself. To do this
you should first have to install docker-registry in any server you have. It should
have a public ip to communicate with your docker nodes.
